Polyaluminum chloride production process on the impact of its application Poly aluminum chloride manufacturers of aluminum chloride synthesis There are many ways, according to the different raw materials, aluminum can be divided into law, the activity of aluminum hydroxide, Aluminum method, aluminum chloride method. 1. Metal aluminum method: The use of metal aluminum synthesis of aluminum chloride raw materials for the processing of aluminum scraps, such as aluminum scrap, aluminum ash and aluminum slag. In the process can be divided into acid, alkali, and 3 kinds of law. Acid method is mainly used HCL, product quality is not easy to control.Alkali production process is more difficult to invest in large equipment and large amount of alkali, pH control costs higher raw material costs.With the most used and the law, as long as controlled Ratio, generally can meet the national standard .2. Aluminum hydroxide method: aluminum hydroxide powder is relatively high, the synthesis of heavy metals such as polyaluminum chloride and other toxic substances is low, the general use of heating and pressure acid dissolving the production process. This process is relatively simple, but the production of polyaluminum chloride low base, so the general use of aluminum hydroxide heating and pressure acid dissolved plus calcium aluminate mineral powder and two processes .3 trioxide Aluminum method: raw materials containing aluminum oxide are mainly gibbsite, bauxite, kaolin, gangue and so on. The production process can be divided into two steps: the first step is to obtain crystalline aluminum chloride, the second step is obtained by pyrolysis or neutralization PAC aluminum chloride manufacturers 4. Aluminum chloride method: the use of chlorine Aluminum powder as raw material, the processing of polyaluminum chloride. This method is the most widely used, mainly in neutralization, electrochemical and thermal decomposition of three 1. Roller poly (aluminum) aluminum chloride content in general, water Insoluble matter, used for sewage treatment. 2. Plate frame poly (co) aluminum chloride aluminum content, low water insoluble, for sewage treatment and drinking treatment. Spray-dried poly (aluminum) aluminum chloride content, low water insoluble, fast dissolution. For drinking water and higher standard water treatment. Spray drying characteristics: As the pressure spray-dried products are porous particles or hollow particles, using pressure spray-drying, and more to obtain the purpose of granular products, the resulting granular products with excellent dust resistance and flow properties. Due to the larger contact area between product and water, wetting performance is better than powdered product, purifying water significantly faster than powdered product, and pressure spray-dried product has unique characteristics Well received by users.
